yt-idefix 0.4.0

An extension module for yt, adding a frontend for Idefix

yt_idefix

A maturing yt frontend for Idefix, packaged as an extension for yt. This frontend is a candidate for integration in the core yt code base.

Installation

Make sure you have Python 3.7 or newer, then run

python3 -m pip install yt_idefix

If you don't already have yt it will be installed along.

Usage

After importing yt itself, make sure to activate the extension

import yt
import yt.extensions.idefix

Then you should be able to load Idefix data seamlessly with yt.load.

Current limitations

As of version 0.3.1 of this project, the frontend allows one to read Idefix's dumpfiles only, through the IdefixDmpDataset class. IdefixVtkDataset may be implemented in the future, but won't be usable directly with yt.load before the next yt bugfix release is available (see bellow).

The IdefixDmpDataset class is functional but far from optimized, it may take much longer than strictly needed to perform queries. This will be adressed in the future.

As of yt 4.0.1:

• Non-uniform grids (using log spacing) are not supported, which makes this frontend of very limited use for Idefix.
• yt.load() is not suitable for vtk files that are not produced by Athena. https://github.com/yt-project/yt/issues/3001 This bug is however resolved on the main branch (https://github.com/yt-project/yt/pull/3424)
